Su Zhao, a modern ordinary person, accidentally traveled to the Ming Dynasty in the 24th year of Hongwu. It coincided with the imperial examination. He wanted to deliberately offend Zhu Yuanzhang in order to die and return to modern times. However, due to some shocking remarks about the predicament of the Ming Dynasty, he was unexpectedly selected as the number one scholar by Zhu Yuanzhang. At the cusp of the change of imperial power and the vassal king's support of troops, Su Zhao was forced to get involved in the court game, facing the weakness of the emperor's grandson Zhu Yunwen, the party struggles of Huang Zicheng and others, and the hidden dangers of the vassal king's support of troops and self-respect. At the same time, Zhu Yuanzhang accidentally connected to the time and space of Chongzhen in the late Ming Dynasty, learned the outcome of the fall of the Ming Dynasty, and secretly planned a strategy to break the situation. Relying on modern cognition, Su Zhao repeatedly clashed with the saints, stated the pros and cons, and wandered on the edge of life and death. While trying to find a way home, he was unknowingly involved in the rewriting of the national destiny of the Ming Dynasty. In the iron-blooded imperial power and the tide of the times, he wrote a legend that spanned time and space and reversed the fate of the dynasty.
